摘要
Full-potential linearized augmented plane wave method has been employed to investigate the electronic and magnetic properties of Ru2VSi Heusler alloy at optimized lattice parameter and in expanded lattice. Present computations predict that Ru2VSi has a ferromagnetic ground state with an optimized lattice constant 5.952 angstrom. The compound in ambient conditions was found to have metallic character. However, increased value of lattice parameter induces 100% spin-polarization in the material at Fermi energy. Further, the band gap tends to increase and the material behaves as pure half-metallic at an increased value of lattice constant.
